It is standard practice in enterprises to analyze large amounts of logs to detect software failures and malicious behaviors. Mobile applications pose a major challenge to centralized monitoring as network and storage limitations prevent fine-grained logs to be stored and transferred for off-line analysis. In this paper we introduce EMMA, a framework for automatic anomaly detection that enables security...
Mobile devices carry a number of vulnerabilities that, when exploited, can result in proprietary-data leakage, data alteration, fraudulent transactions and, in extreme cases, physical damage to the user and surroundings. Such attacks can be instigated by both outsiders and insiders, and can leverage vulnerabilities embedded in the hardware and software components of the device, as well as risky behavioral...
The current mobile application distribution model cannot cope with the complex security requirements of the emerging "bring your own device" (BYOD) paradigm. A secure metamarket architecture supports the definition and enforcement of BYOD policies and offers a promising prototype implementation tested under realistic conditions. The Web extra at http://youtu.be/0hEJoGhzczs is a video slideshow...
An agile, lightweight, but secure extensible hybrid application container and deployment mechanism for mobile devices has the potential to provide improved cross platform support, reduced development lifecycle time and a consistent application security model within large organizations. We demonstrate how such an architecture can provide a set of security and mobile device management interfaces to...
The modern mobile ubiquitous computing environment, with reasonable connectivity, processing power and sensing capabilities on portable devices, present applications and services with the opportunity to be truly context-aware. But building context-aware applications has large development overheads due to complexities of sensing, aggregating and inferencing context information. To reduce the developers'...
Maintenance of critical emergency infrastructure is potentially lifesaving, but also expensive and tedious to document and track. In this paper we demonstrate a maintenance system based on Near Field Communication (NFC). NFC-enabled mobile phones and NFC tags are used to improve recurring maintenance processes: the maintenance task itself becomes more efficient; and the system facilitates real-time...
Given the wide acceptance of SMS in mobile devices,it has been applied in unconventional applications beyond chating and exchanging short text messages. In this paper, we review a set of unconventional SMS-based applications. We review the basic operation modes in which they act and their needs for security services. Considering limitations on mobile devices, here we propose an architectural model...
